Hello, was looking for some help on extracting a field from the passwd file.
So far I have made a copy of the passwd file and changed my rights so I can edit it. Every user's password is coded as an :x:, and my goal was to change that x to a blank, and then try to extract any user with that field... (2 Replies)

getpwent
GETPWENT(3) Linux Programmer's Manual GETPWENT(3)NAME
getpwent, setpwent, endpwent - get password file entry
SYNOPSIS
#include <pwd.h>
#include <sys/types.h>
struct passwd *getpwent(void);
void setpwent(void);
void endpwent(void);
DESCRIPTION
The getpwent() function returns a pointer to a structure containing the broken out fields of a line from /etc/passwd. The first time it is
called it returns the first entry; thereafter, it returns successive entries.
The setpwent() function rewinds the file pointer to the beginning of the /etc/passwd file.
The endpwent() function closes the /etc/passwd file.
The passwd structure is defined in <pwd.h> as follows:
struct passwd {
char *pw_name; /* user name */
char *pw_passwd; /* user password */
uid_t pw_uid; /* user id */
gid_t pw_gid; /* group id */
char *pw_gecos; /* real name */
char *pw_dir; /* home directory */
char *pw_shell; /* shell program */
};
RETURN VALUE
The getpwent() function returns the passwd structure, or NULL if there are no more entries or an error occurs.
ERRORS
ENOMEM Insufficient memory to allocate passwd structure.
FILES
/etc/passwd
password database file
